| description | The present invention discloses a method to detect lead in spice with an AOTF near infrared spectrograph, which comprises procedures below: A. Calibrating samples are prepared according to actual situations of tested spice solution and a specific lead content grade; B. The AOTF near infrared spectrograph collects near infrared spectrum data of the calibrating sample; C. A rated calibrating model is created based on relevant data of the near infrared spectrum data corresponding to the lead content; D. Near infrared spectrum data of the spice sample to be tested are collected; E. Lead content of the spice sample to be tested is analyzed in light of the calibrating model above to measure lead content in the spice sample to be tested. The present invention has the advantages of unnecessary sample preprocessing, quick detection (second-level), no reagent consumption, pollution-free and environment-friendly analysis and high accuracy, etc. |
